Abstract
The utility model provides a kind of wind power principal axis ring flange just forger dress, comprises forging die and conical surface upset plate, and the forging and stamping working face of conical surface upset plate is in the taper seat going to push up to lower convexity.The forging and stamping working face of conical surface upset plate is in the taper seat going to push up to lower convexity, in wind power principal axis ring flange just forging process, by applying pressure to conical surface upset plate, make forging under the effect of this kind of conical surface upset plate working face, be pushed outwardly, instead of also have very large frictional force only to forging vertical depressing force as existing plane upsetting plate working face, make wind power principal axis ring flange just forge time decreased, improve wind power principal axis ring flange and just forge efficiency.After just forging, adopt the upper anvil with flat working face to continue jumping-up die forging, finally complete the die forging of wind power principal axis ring flange.
Description
Technical field
The utility model relates to wind power plant manufacturing technology field, is specifically related to a kind of wind power principal axis ring flange just forger dress.
Background technology
Wind-power electricity generation is the clean energy resource generating that country advocates energetically, at the positive development of China, main shaft is an assembly of wind power plant, along with continually developing of wind energy, main shaft demand also increases thereupon, and how to raise the efficiency when ensureing product quality is the core that current forging industry is competed.Because ring flange is thin, diameter is large, and axle body is thin, and step difference is large, adopts that open die forging is time-consuming requires great effort again.Fig. 1 shows existing a kind of wind power principal axis ring flange die forging frock, and comprise forging die 2 and upper anvil 1, the forging and stamping working face of upper anvil is plane, in wind power principal axis ring flange jumping-up forging process, all the time adopt the upper anvil of this flat working face to forge and press forging, length consuming time, forging efficiency is low.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of wind power principal axis ring flange just forger dress, improves forging efficiency.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A wind power principal axis ring flange just forger dress, comprises forging die and conical surface upset plate, and the forging and stamping working face of conical surface upset plate is in the taper seat going to push up to lower convexity.
Above-mentioned wind power principal axis ring flange just forger dress, the cone angle of taper seat is 145 °-155 °.
Above-mentioned wind power principal axis ring flange just forger dress, the cone angle of taper seat is 150 °.
Above-mentioned wind power principal axis ring flange just forger dress, forging die comprises upper die body and lower mold body, and ringwise, lower mold body center has leakage shaft through-hole to upper die body, and upper die body is arranged at lower mold body upper end and lower mold body surrounds die cavity jointly.
The forging and stamping working face of conical surface upset plate is in the taper seat going to push up to lower convexity, in wind power principal axis ring flange just forging process, by applying pressure to conical surface upset plate, make forging under the effect of this kind of conical surface upset plate working face, be pushed outwardly, instead of also have very large frictional force only to forging vertical depressing force as existing plane upsetting plate working face, make wind power principal axis ring flange just forge time decreased, improve wind power principal axis ring flange and just forge efficiency.After just forging, adopt the upper anvil with flat working face to continue jumping-up die forging, finally complete the die forging of wind power principal axis ring flange.
Accompanying drawing explanation
Below in conjunction with accompanying drawing to the further detailed description of the utility model:
Fig. 1 is the schematic diagram of existing wind power principal axis ring flange die forging frock.
Fig. 2 is structural representation of the present utility model.
In figure: 1 upper anvil, 2 forging dies, 3 conical surface upset plates, 4 forging dies, 5 upper die bodies, 6 lower mold body.
Detailed description of the invention
As shown in Figure 2, a kind of wind power principal axis ring flange just forger dress, comprises forging die 4 and conical surface upset plate 3, and the forging and stamping working face of conical surface upset plate is in the taper seat going to push up to lower convexity.
Particularly, the cone angle of taper seat is 145 °-155 °.
Particularly, the cone angle of taper seat is 150 °.
Particularly, forging die comprises upper die body 5 and lower mold body 6, and ringwise, lower mold body center has leakage shaft through-hole to upper die body, and upper die body is arranged at lower mold body upper end and lower mold body surrounds die cavity jointly.
